The Arm Cortex-M family now has five processors. In this paper, we compare the features of various Cortex-M processors and highlight considerations for selecting the correct processor for your application. The paper includes detailed comparisons of the Cortex-M instruction sets and advanced interrupt capabilities, along with system-level features, debug and trace features, and performance comparisons.
Since writing this block we have announced further additions to the Cortex family, Cortex-M23 and Cortex-M33, and updated the document. The latest version is available here: Cortex-M for Beginners - An overview of the Arm Cortex-M processor family and comparison (2017).
Arm Cortex-M23 and Cortex-M33 are the first embedded processors using the Armv8-M architecture, bringing the proven secure foundation of Arm TrustZone to the most constrained IoT nodes.

Thanks for very useful document!
Now I'm trying to translate this into Japanese and post my blog.
Can I use some pictures from this? (of course with appropriate quotes)
Extreme usefulness, Joe. Best Regards
very useful document
It's a common error a user can make in Arm Information Center.
daith has a discussion about this matter
Getting a link to an Arm documentation page or pdf.
